Exam XK0-005 topic 1 question 40 discussion

D. cat toDelete.txt | xargs rm -rf The "cat toDelete.txt" command will display the contents of the "toDelete.txt" file, which contains the names of the files and directories to be deleted. The "xargs rm -rf" command will take the standard input from the "cat" command and pass it as arguments to the "rm" command. The "-rf" options of the "rm" command are used to forcibly delete the specified files and directories, including any files and directories within them, even if they are write-protected. The "xargs" command is used here to process the input one line at a time and execute the "rm" command for each line.

The rm command will do nothing to act on the contents of the file without help. As written rm will remove the file in question. You need to expose the contents of the file to rm in order for it to act on them. Either cat the file and hand it off to xargs or "xargs rm -rf < file" or cat it , send it to awk and let awk pass the contents to rm.

D. `xargs` builds and executes command lines from standard input. Assuming the file, toDelete.txt, contains one file name per line, this works. The other answers are nonsense.

mod correct, the question states "sobelete.txt" and should say "toDelete.txt".

Definitely is D

Tested, confirmed D is correct

D is the correct answer. The selected answer delete the file. with answer D it removes the files listed inside the file. xargs - build and execute command lines from standard input.

I'm pretty sure this one is D. Option B just removes the file, but the question asks to remove files & directories "listed inside" the file. Just tested this out on my Linux machine ... It's D
